Thought I should update, I was biching before about TCC lockup and my A50 controller.

I finally swapped it out for an A40 and the truck has changed 10 fold. I would have to recommend anyone that has an A50 controller truck to do the swap.

My truck shifts way firmer now and quicker doesn't feel like a slush box and consistantly now locks the TCC when its supposed to. Its way more fun to drive and works way better day to day, I also now have the ability which I used to adjust when the TCC locks up etc

Now I beleive it is working how it was designed to!

Mike are you saying that the "improvement" is only temporary?

I too had a lot of complaints about my 09 and was considering buying an A40 TCM.

Do you vote yes or no?

I've tried it a couple of times and found it was temporary as far as shift quality. As far as the TCC, I have no experience with that part of it.

Shift quality is the least of my concerns it can be quick and soft, its the TCC Im concerned about and its finally consistant.
